Smurf hat

From Smurfology

A Smurf hat is a piece of clothing generally worn by all Smurfs. It resembles a standard woolen cap with the top part of it flopping forward (or in any preferred direction, as with Slouchy's hat). Male Smurfs generally wear Smurf hats because the top of their heads are bald. Female Smurfs tend to wear them simply to identify themselves as Smurfs.

Smurf hats may also vary in appearance depending on the type of Smurf wearing it. Greedy, who is the village chef, wears a Smurf hat that is a variation of a chef's hat.
